Film one: A very intelligent surgeon kidnaps people to use in his sordid experiment. He wants to create a new sub-species; the human centipede. By placing three victims anus to mouth he creates an experimental operation to create an animal that has a single alimentary canal i.e. what goes in will come out; and go in and go out; back in and out again finally. With Faeces moving through three digestive systems, each victim gets a worse fate than the last.

Film two: A mentally unstable man decides to do the same but with twelve people. He is no surgeon just a security guard who lives with his abusive mother. He uses staple guns and duct tape so it’s a bit of a hash job He is obsessed with the first film in this second instalment and has a scrap book like the surgeon’s drawings in the film. He gets impatient with the process and uses laxative to initiate the digestive process. He also rapes the centipede from behind and takes advantage of the sordid and stinky situation.

“The chief pleasure on offer seems to be wallowing in the spectacle of sadism (including sexual sadism) for its own sake."
